The survey polled 6,700 companies worldwide, including 200 from the Chinese mainland, said Dominic King, Grant Thornton's global research manager.

King added that the survey also showed that State-owned enterprises have a better record than private and foreign companies in China for placing women in senior positions.

The concept of "opportunity for all" is deeply embedded in Chinese society and has boosted gender equality, he said. Rapid urbanization, which allows more women to work, plus reduced child care burdens stemming from the family planning policy also are factors, he said.

Jiang Yongping, a researcher at the Women's Studies Institute of China, said she agrees with King's views, adding that the family planning policy in urban areas also ensures that girls get equal access to education and other resources.

Jiang said society has shown growing confidence in women's management skills, and women leaders are often regarded as more considerate and caring when compared with male leaders.

But although China has achieved remarkable progress in breaking the glass ceiling for women in business, it still lags behind in terms of providing sufficient support for career women.

Only 30 percent of companies on the Chinese mainland allow flexible working hours for career women with children, compared with 63 percent of companies worldwide.

Less than a third of Chinese mainland employers provide extra unpaid holidays apart from maternity leave for career mothers, a figure lower than the global average.

The survey also found that only 15 percent of businesses on the mainland provide training programs that facilitate a path for female employees to senior executive jobs.

Nearly seven in 10 companies admitted they never considered tailored training workshops for women employees.

Kathleen Chien, chief operating officer of 51job.com, a major recruitment website in China, said it is important for women to seek help when they need it, both at home and in the workplace.

"A lot of women try to take on too much at the same time without asking for help. They are often embarrassed or feel guilty about asking for assistance or special treatment.

"I think in this day and age, most employers are willing to make accommodations to help as much as possible if that ultimately allows them to retain good talent," she said.

More workers have women bosses: survey

Eighty percent of employees have female bosses in 2014, an increase from 68.3 percent in 2013, a recent survey showed.
